Abstract

Soil insects are a group of organisms whose existence is highly dependent on their microhabitat. Its presence is indispensable because of its ability to reform and decompose organic matter. The presence of soil insects illustrates the functioning of a habitat. This study aims to analyze abiotic and biotic environmental conditions in several types of soil insect habitats on the island of Lombok and securitize the level of similarity of insect species in each of these habitats. The research method used in determining the initial sample point in each habitat is purposive sampling. The parameters observed are those thought to influence the presence of soil insects, including parameters of the abiotic environment and parameters of the biotic environment. The results obtained were that the soil insects found in forest, garden, mangrove, and mining habitats had a high degree of similarity. Forest and garden habitats have a preferred micro-habitat because of the high levels of organic C, moisture, total N, and neural soil pH as environmental factors that most support the existence of soil insects

Summary

Introduction

Soil insects are a group of microarthropods whose existence is highly dependent on their microhabitat. Microhabitat describes habitat conditions suitable for the life of an organism. The response of soil insect groups to environmental conditions determines their ability to use the microhabitat. According to Madej et al (2011), environmental conditions such as food availability, temperature, humidity, pH, and light intensity vary from one microhabitat to another. Soil insects are one of the dominant communities in soil habitat. Its presence is indispensable because of its ability to remodel and decompose organic matter. According to Rohyani (2020), soil insects play a role in overhauling organic material, parasites, and predators (2018), Insects are one of the groups of animals that have a high level of diversity and a high number of individuals covering 70% of all species on earth. Soil insects have strong ecological interactions with their environment, so they have the potential to be used as bioindicators in an ecosystem
